Verify and correct US mailing addresses in bulk. Get standardized addresses with Zip+4, delivery point codes, and congressional districts — with optional geocoding and driving distance add-ons.
Go to tool pageHead to the Address Verification page. You'll see a brief overview of the tool and a file upload zone at the top. No account is needed to get started — you can try the tool as a guest.
Drag and drop your file into the upload zone, or click "browse" to select it. We support CSV, Excel (.xlsx/.xls), TSV, and OpenDocument (.ods) files with up to 20,000 rows. Your file should contain address data — it can be split across columns (street, city, state, zip) or combined in a single column.
Tips
Our AI analyzes your file and automatically detects which columns contain address, city, state, and zip code data. Each mapping shows a confidence score so you can see how certain the detection is. If anything looks wrong, you can manually adjust the mapping by selecting a different column from the dropdown.
Tips
Address Verification includes three optional add-ons you can enable: Geocoding (adds latitude/longitude to each verified address, +$0.02/row), Driving Distance (calculates distance and travel time from each address to a hub point, +$0.04/row), and Demographics by Zip (attaches 41 Census/ACS columns — population, income, housing, employment — by verified zip, +$0.02/row). Toggle them on or off based on your needs.
Tips
Before you pay, you'll see a free preview of the first rows processed with real results. The preview shows the corrected address, Zip+4, match status, and any add-on data. You'll also see the total cost based on your row count and the per-row rate ($0.02/row for verification, $19.95 minimum).
Tips
Once processing completes, your full report is ready. You can view results in an interactive table in the browser, with summary statistics and a map view if geocoding was enabled. Download your results as CSV, a multi-tab Excel workbook with charts and summary stats, or a branded PDF report.
